LEGACY_OPEL/HYUNDAI_KIA/NISSAN/FORD/VOLVO getCategoryTree built the
returned tree from the freshly-parsed PL24 list with
`externalIdToUuid.get(c.code) ?? c.code`, falling back to the RAW upstream
linkPath as the node id whenever a row wasn't in the map. That happened
because the two legacy blocks (unlike the PSA block) did not dedupe by
name, so onConflictDoNothing silently dropped name-colliding rows; those
nodes then leaked a raw `group.action?catId=…` id, which the frontend
turned into `/categories/group.action?...` → 404 "Bir hata oluştu".
Extract the duplicated build/persist into persistAndBuildLegacyTree which:
filters nav-crumb junk + dedupes by name, always re-selects after insert
(never trusts .returning()), and builds the tree FROM the DB rows so every
node id is a real UUID. Deterministic ORDER BY for stable tree order. PSA
block left untouched (it intentionally supports non-UUID PSA codes).
